Respiratory system is the group of tissues and organs in the body that allow us to breathe. Major organs in the respiratory system are mouth and nose, airways, lungs, and diapharm. When the "Inhale" button is pressed, light boxes will be lit up and started flowing to demonstrate the inhale process : diapharm moves downward, lungs get bigger and air goes into the lung. When the "Exhale" button is pressed, diapharm moves upward, lungs will become smaller and air starts to flow out from the human body. The "Breathe" button is used to demonstrate the entire breathing process.
